This movie may have come out at the same time as the movie "Battleship," but it had a lot more thought behind it than the bigger-budget movie based on a '60s board game.
First off, ignore the cast and special effects, and consider the plot: The USS Enterprise carrier group is sunk in minutes by an unknown enemy after its electronics are disabled by an "EMP weapon," barely giving them time to send out a mayday. Only a large debris field is found by satellite. The USS Iowa is in the area on her farewell goodwill tour, and happens to be nearby when an island whose ownership is disputed by North Korea is attacked by missiles and destroyed by the same unknown enemy.
The Iowa engages the enemy, which seems to be not only Stealth-enabled, but actually invisible to the naked eye, though they do appear when they launch their missile attacks. The Iowa is also attacked with the EMP weapon, but thanks to the ship's legacy 1940's no-computer technology, and the presence of a skilled team of naval historians on board to restore the Iowa to her WWII condition for her new destiny as a floating museum, she is still able to fight on in her not-inconsiderate WWII level of combat readiness.
As the captain, crew (and hesitant Admiral) attempt to maintain contact with the enemy until reinforcements arrive, they try to figure out who is behind the attacks.
The CG effects are pretty bad. The acting is not much better. But the idea that the low-tech -- yet formidably-armed -- Iowa might be the best possible fighting platform against a technologically-advanced enemy is a concept worthy of better treatment. Certainly better than "Battleship" provided.
